17- Claims. (o1. 56-464) This invention relates to a grain handling machine, and particularly to a device adapted to be used to raise grain afterit has been out.

One form of the invention is applied to a com bine. The entire machine is moved overa field upon which cut grain lies. The pick-up is operated and the grain is raised from the field and deposited in the carrier of the combine and moved from it into the machine where it is threshed and separated in the usual manner. One. of the objects of the invention is, therefore, to provide means for picking up out grain. Another object is to provide a pick-up attachment which may be detachably mounted on the combine and used to pick up the grain. When so used, the pick-up attachment is preferably. driven from the power source which drives the mechanisms of the combine. Other objects-will appear from time to time in the course of the specification and claims.

The invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:

Figure l is a plan view of a combine with the pick-up attachment mounted upon it;..

Figure 2 is a plan view of the pick-"p attachment on an enlarged scale, with parts broken away and parts in section;

Figure 4 is a longitudinal, vertical cross sectiontaken on line 4-4 of Figure 2;

Figure 5 is a transverse cross section taken on line 5-5 of Figure 4; Figure 6 is a detailed cross section on an enlarged scale taken on line 6-6 of Figure 5.

Like parts are designated by like characters throughout the specification and'drawings.

As shown in Figure 1, the main body of the combine is indicated at A. It is carried on wheels A A It is provided in its forwardend with a steering wheel A A3 is a boom pivotally mounted on the combine frame at A carrying in its outer end a supporting wheel A A is a brace for the boom. A is a compensating supporting assembly which serves to balance and support the carrier A which is supported from the boom by means of members'A A A is an elevator communicating with the carrier A and by means of which grain which has been deposited on the carrier A is moved laterally, is raised and deposited into the separator;

B, B are supporting arms adapted to be'fastened to the framework which'carries the car'- rier A and to carry the pick-up mechanism. The

Figure 3 is a side elevation of the pick-up atpick-up mechanism includes, generally a continuous belt conveyor upon which slats and pick-up members are mounted. The conveyor is divided into two off-set sections which move together but provide means for spacing the slats and pickup parts of one sectionalternately with those of another so that while 'th'e'pick-up members of one section are in contact with the ground those of the adjoining section are not. B B are end plates mounted one at each end-of the frame. These plates serve to support the mechanism of the pick-up assembly. B B? are shoes, preferably spring shoes. Each of them is fastened to one of the arms B as at B and provided with a ground contacting portion 13 and an adjustable'support B This support is pivotally fas tened to the portion B at B and provided with a plurality of perforations B by means of which it may be adjustably positioned on the arm B to which its other end is attached. The end plates B B -are slotted as at B The adjust-. ment of the member B is to adjust the height of the pick-up assembly with relation to the ground. 5

C is a bearing housing. One of such housings is mounted ineach of the frames B and is provided with, an opening C within which is slidably *mounted a bearing'block C Anadjusting bolt C is provided and carries upon it nuts 0, C. By means of the bolt and nuts the bearing blocks C may be raised andlow'ered. J ournaled within the bearing blocks C C is the lower conveyor shaft C This shaft carries a plurality of sprockets C Journal'ed in suitable bearings C adjacentthe upper part of the plate B is a sec- 0nd or upper conveyor shaft C This'shaft carries three sprockets C C one of which is positively placed with respect, to, each of the sprockets C 0 C are link belts or chains of Which there are three, one engaging each upper and lower pair of, sprockets C 0 By means of this construction the upper and lower shafts rotate together.

D is a generally upright supporting member fastened to the member B. ,A generally similar member. D is mounted at the opposite end of thestructu're to the other member B. It is provided at its top with an enlargement D The bearing blocks C", C are supported in the members D, D and may be formed integral with them. Since the upper shaft C passes through the bearing members C which are carriedin the up-rights D, D and since the side plates B B which carry the lower shaft C arepivotally mounted about the center of the shaft 0 the manner to be described below.

the entire pick-up structure may rotate through nected with the sprocket D by a chain D Through suitable driving mechanism connected generally by D the sprocket'D is driven pref erably from the separator mechanism andthus the pick-up mechanism is driven;

E,.E are supporting and stiffening members fastened to the side plates B 13 and extending laterally across thepick-up assembly. Fastened to the upper member E are a plurality of bearing blocks E E shaft isbent about the .upper members E and extends These blocks carry the upper downward and is bent and fastened about the lower-member E.- E E are a plurality of bearing blocks supporting the lower shaftC E is a protecting hoodor cover bent about the bearing blocks E 'and overlying a part of the cover plate E andresting upon the lower member E. Guiding bars or pins E are positioned-inperforations E in the bearing blocks E These guiding pins E are slidably mounted in perforations E in the lower member E. l? is a central bearing block supporting thelower shaft C It is provided with an adjusting bolt E which has upon it nuts E The bolt E passes through the lower member E and is threaded ina plate E which is fastened to the lower memberE.

F, F are side arms which support the reel in They are pivotally mounted on the outside of the bearing member C". F yF are supporting stops which limit the lower pivotal movement of the arms F but permit them to rise upwardly. Adjacent the.

free ends of the members F- each carries a hearing F Within this bearing is journaled a shaft F -which carries at one end a sprocket: Mounted onthe shaft area plurality of arms F which carry and are connected by vanes F F is a stub shaft supported on one of the arms F and carrying a'gear F which meshes with the gear F on the upper shaft 0 F is a sprocket mounted on the shaft F F is a chain connecting the sprockets F and F By means of the chain the sprocket F and the shaft F are driven from the upper'shaft C 1 G, Gfare upwardly extending supporting members mounted at their lower ends each upon one of the members B. G G are additional supporting and bracing members mounted each at its lower end upon one ofthe members B and joined at its upper end to one of the members G. The members G are provided at their upper ends with a laterally bent part G2 within which is positioned aneye bolt G which may be adjusted as to position by means of nuts G. G is a spring fastened at its upper end in the ring G of the eye boltG At its lower end as at G each of the springs is fastened to the side members B or toa part-which is fastened to the side members B Thus through the springs the pick-up attachment is mounted so that it may rise and fall through a limited pivotal movement. In passing 7 over anobstacle the pick-up assembly may pivot upwardly. f When the obstaclehasbeen passed it E is a protecting cover or shell which do not prevent upward movement.

H are slats. As above mentioned each slat extends practicaily only about one-half of the width of the pick-up mechanism. The slats on one side are off-set with respect to those on the other. The slats of one set are, however, identical inconstruction with those of the other set. Each slat is mounted at its outer end to the outer sprocket chain C and at its inner end to the inner sprocket chain C The chains are provided.

with special links H having laterally extending attaching parts H to receive the slats. on each: of the slats gers H It will be obvious that while I have shown and described an operative device, many changes might be made in the size, shape, number, relation and distribution of parts without departingmaterially from. the spirit of, my invention, and I wish therefore that my description and showing be considered as in a large measure diagrammatic.

The use and operation of this invention are as follows:

The. pick-up assembly may be built integrally with the combine and may form a permanent part of it. It may also be used as a removable attachment for a combine. In the latter case. when it is desirable to use the pick-up, it is attached to a combine in the position shown in the Mounted is a plurality of inclined findrawings, particularly as shown in Figure 1. In

thatposition it is mounted along the forward edge of the carrier and is connected with the driving mechanism which drives the carrier and the separating mechanism within the combine. twill be understood of course, that any form of drive might be used and the pick-up might be actuated separately. It'is sufiicient for the purposes of this invention that rotation be given to the rotary parts in the picleup. When the pickup mechanism is in the position shown, its po-v sitio-n above the ground may be raised or lowered by adjustment'of the eye bolts G The belt will,v of course, be tightened by adjustment of the bolts C which adjust the lower shaft C together with the general central adjusting bolt E Withthe parts in the properly adjusted position and with the pick-up mechanism connected with a power source, the combine is moved acrossa field upon the surface of which grain is lying.. The pick-up elevator rotates in the direction shown 'by the arrowin Figures 3 and 4 and the reel rotates in the opposite direction as indicated by an arrow in Figures 3 and 4. The pick-up fingers contact the grainon the surface of the field and raise it, and they, together with the slats, carry it backward and upward and deposit it upon the main carrying conveyor A This is moved toward the separating part of the combine and the grain is carried thence to the elevator A and'into the separating zone. The reel, with the vanes F serves to assist in keeping grain on the pick-up conveyor and it also somewh'atassists the conveyor in carrying the grain backward.

- The eye-bolt member G may be adjustedup and down by means of nuts G G4. When it is adjusted upwardly to increase the tension on the viously rise more readily from'the ground; This adjustment may be made to suit the conditions of:

operation. 1

I As has been stated above, thepick-up may.

pivot upwardly about the center. of the shaft C stone upon the ground. The upward movement :of: the reel the volume of material'passingunder it; Since the material passes between thereel and the belt assembly of the pick-up, as'a large volume of material enters, it willtend to cause the reel to pivot upwardly. This reel further tends to hold the grain in contact with the. traveling conveyor of the pick-up during the time of pick-up'move ment. It thus serves as an important function of its operation also to prevent the materialion' the pick-up conveyor {from being. blown .away.

is clear that during the travel of the slats. from sprocket to sprocket the fingers have a constant speed of movement. When, however, the belts of the pick-up move about either the forward or rear sprocket, the fingers swing outwardly, and they thus at these periods and in'these positions have an increased peripheral velocity and their raking and pick-up action and their discharging action is greatly improved thereby.
